We report new oribatid records from the western Antarctic Peninsula region obtained during the XXIV and XXVI–XXVIII Ukrainian Antarctic expeditions. Five species (including 2 subspecies) representing five families of oribatid […]
Polar microalgae are microscopic organisms adapted to survive in cold and extreme habitats such as sea-ice, glaciers, lakes and snow. These microorganisms provide an essential basis as primary food sources […]
Improved methods for identifying species at risk are needed to strengthen climate change vulnerability assessments, as current estimates indicate that up to one million species face extinction due to environmental […]
The Beaufort Gyre (BG) is an important feature of the Arctic Ocean. By accumulating or releasing freshwater, it influences ocean properties both within the Arctic and as far as the […]
An algorithm is presented for path-planning in a non-uniform spheroid mesh containing exclusion zones, vector and scalar fields. The mesh models physical environments such as ocean regions, together with a […]
Understanding how species survive at their poleward limits of distribution is of interest in species conservation, particularly in light of global warming and predictions of shifting distributions of both predators […]
Comets tails can reveal information about the local solar wind conditions. They can exhibit various signatures of interactions with the solar wind including bending, developing kinks, and sometimes undergoing tail […]
Benthic foraminiferal assemblages are useful tools for paleoenvironmental studies but rely on the calibration of live populations to modern environmental conditions to allow interpretation of this proxy downcore. In regions […]
Long-term variability and tendencies in monthly mean semidiurnal tide (12-hr) in zonal (U12) and meridional (V12) winds are investigated in northern polar mesosphere and lower thermosphere (MLT; ∼80–100 km) using […]
Ground-penetrating radar reveals subsurface geometry and ice stratigraphy that contains information about past and present dynamics of the cryosphere. Synthetic Aperture Radar (SAR) is a processing technique based on averaging […]
The Cordillera Darwin Icefield (CDI) in Tierra del Fuego is one of the largest temperate ice bodies in the Southern Hemisphere. We simulate the climatic energy and mass balance of […]
